我怎样才能用 python3 中的频率发出声音?

How can i make sound with frequency in python3?

我试过了,但它只生成了一个空行:

import os
a=300
b=2000
os.system('play --no-show-progress --null --channels 1 synth %s sine %f' % ( a, b))

在 Python 中播放给定频率和持续时间的提示音的简单方法:

frequency = 1000 # Hertz
duration  = 2000 # milliseconds

Windows:

import winsound
winsound.Beep(frequency, duration)

Linux:

# SoX must be installed using 'sudo apt-get install sox' in the terminal
import os
os.system('play -n synth %s sin %s' % (duration/1000, frequency))

macOS:

# First install Homebrew (https://brew.sh/) 
# and then SoX using 'brew install sox' in the terminal
import os
os.system('play -n synth %s sin %s' % (duration/1000, frequency))

跨平台

使用 PyAudio 模块和一些编码:
